Airport Magazine- April/May 2012

including front-mounted brooms, multi-task snow
removal equipment, severe-duty plow trucks and
large capacity rotary plows, along with other inno-
vative applications of airport equipment.

For many years, MHT would clear around elevated lights with small pickup plows and hand shovels. During this very laborious activity, several lights would be broken, which became a burden to the airfield lighting budget.

There have been several “light-clearing” plow designs, and most have had some success. We married a New Holland TV145 with the Fortbrand VAMMAS light clearing plow, then raised the tractor by replacing the turf tires and wheels with a set of 14.9R46 (tall, thin agricultural) wheels and tires. These tires and wheels provide 24 inches of clearance, which allows the tractor to traverse safely over the top of the elevated runway and taxiway lights.

Light clearing now can be completed within a
single eight-hour shift with little or no damage.
The procedure includes working with two rotary
plows, thus eliminating any windrows. During an
extended storm and/or storms of great accumula-
tions, a light-clearing crew can operate under the
control of the snow boss without the need of put-
ting a crew member out into the elements.

RECENT INNOVATIONS

The most recent innovative technology application is our in-pavement snow melters. In 2010 MHT began a project to replace four existing snow melting pits. The existing units were installed in 1993 and were designed to melt approximately 120 tons of snow per hour at each of the two locations. As the airport grew and these melters aged, replacement was required and capacity was increased.

The project was awarded to a local contractor, and Trecan Snow Melters were employed to provide 300 tons per hour snow melting capacity at each of the two locations. The melters utilize natural gas for fuel. Besides being the most modern design and offering reduced operating cost, these melters can be operated and monitored remotely from the cab of the ramp plow pushing the snow into them. This single operator operation is the most efficient snow melting available.

The terminal ramp plows always have pushed
snow into the melters at each location. During the
